Homework help plzzzzzz?

24. After taking a shower, you notice that small droplets of water covers the mirror. Explain how this happens, describing where the water comes from and the changes it goes through.



25.An iceberg is floating, partially submerged, in the ocean. At what part of the iceberg is the water pressure the greatest?



26. Use Boyle's Law to explain why %26quot;bubble wrap%26quot; pops when you squeeze it.



27. Compared with an empty ship, will a ship loaded with plastic foam balls float higher or lower in the water? explain.



28. Inside all vacuum cleaners is a high-speed fan. Explain how this fan causes dirt to be picked up by the vacuum cleaner.Homework help plzzzzzz?
24. the water condenses on the mirror because the air is relatively humid. it comes from the vapor released by the water in the shower. it changes from a gas to a liquid.



25. water pressure is the greatest at the bottom because there is pressure from the top of the iceberg as well as all of the pressure caused by the surrounding water above it.



26. as pressure increases, the volume will try to decrease in the bubble. at a point, it cannot take it anymore and it pops.



27. it should float lower because the plastic foam balls do not necessarily affect the outside shape or density of the outside material of the ship which helps it float.



28. because the high speed of the fan creates low pressure around the area, the high pressure from the outside pushes the dirt to be picked up by the vacuum cleaner.Homework help plzzzzzz?
look through your texbook. dont they have the answers in there? it all has to do with WATER CONDENSATION...look that word up . or either FOG, or WATER PRESSURE....etc
